Liquefaction induced kinematic loads on piles and inertia loads - literature review and recommendations for design
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Earthquake shaking can cause soil liquefaction in certain types of soil. The associated loss of soil strength and stiffness coupled with any lateral ground movement can be damaging to buildings and their foundations. Pile ...
Method for the explicit consideration of ground motion duration in NZS 1170.5
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Recent studies have demonstrated that longer earthquake ground motion duration can reduce structural deformation capacity and increase collapse risk. This study introduces a method to explicitly account for such effects ...
Assessment of lateral spread potential used smeared strengths of liquefied/non liquefied soils
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Liquefaction-induced lateral ground displacements (lateral spread) are typically assessed using empirical methods where a continuous weak (liquefied) layer is expected. These methods are not appropriate for variable fill ...
The next generation of drywall construction for low-damage design
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Low-damage structural systems that can withstand large earthquakes with no structural damage, or localised damage in pre-defined fuses, have become commonplace in the past one to two decades. These systems however, generally ...
A displacement-based design method of low-damage dual systems with hysteretic and nonlinear viscous energy dissipation
(New Zealand Society for Earthquake Engineering, 2023-04-19)
In 2019, a large shaking-table test was performed for a full-scale two-storey low-damage concrete wall building. The test building comprises unbonded post-tensioning (UPT) rocking walls and perimeter frames in both directions. ...
Performing Structural Assessment using Acoustic Measurements
(New Zealand Society for Earthquake Engineering, 2023-04-19)
Natural hazards, such as earthquakes, could be catastrophic. One challenge that society faces is how to provide a rapid and accurate evaluation of the structural damages after the events. Traditional visual inspection is ...
